Problems solved by technology
However, the current compensation method has the following unavoidable problems. As the voltage decreases, the reactive power compensation capability decreases quadratically; the capacity of compensation equipment is usually designed to be 20% to 30% of the installed capacity of the wind farm, which increases the construction cost of the wind farm. , and the operating loss cannot be ignored

Description
technical field [0001] The invention relates to the technical field of wind farm power generation control, in particular to a virtual synchronous generator field control platform device for wind farm power generation control. Background technique [0002] At present, the characteristics of wind power grid-connected development are large-scale, highly concentrated, and long-distance, and large-scale and highly concentrated wind power is mostly located in remote areas, with small loads, less thermal power and hydropower, weak power grids, and its development speed lags far behind wind power development. Wind power disturbances have a wide range of impacts. As the proportion of wind power in the grid increases year by year, grid dispatching tasks are heavy and risks are high. The main problems are the coordinated voltage control of the grid and wind turbines under large-scale wind power grid connection, the support of wind turbines to the grid (primary frequency regulation and ...
